Control of solid state memory device temperature using queue depth management
Embodiments relate to controlling a temperature of a solid state memory device using queue depth management by monitoring an operating temperature of each of a plurality of solid state drives of the solid state memory device. Based on a determination that the operating temperature of one of the plurality of solid state drives exceeds local device threshold values, the method includes receiving an indication that one or more local measures have been taken by the solid state memory device. Based on a determination that the operating temperature of one of the plurality of solid state drives exceeds a secondary global threshold value, the method includes reducing a queue length for the solid state memory device.
1. A computer program product for controlling a temperature of a solid state memory device using queue depth management, the computer program product comprising:
a tangible non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
monitoring, by a processor, an operating temperature of each of a plurality of solid state drives of the solid state memory device;
based on determining that the operating temperature of one of the plurality of solid state drives exceeds a first threshold value, receiving an indication that one or more local measures have been taken by the solid state memory device;
based on determining that the operating temperature of one of the plurality of solid state drives exceeds a second threshold value, reducing a queue length of the solid state memory device, wherein an amount of the reduction of the queue length is based on a rate of change of an ambient temperature of an environment of the solid state memory device;
based on determining that the operating temperature of all of the plurality of solid state drives are below a third threshold value, resuming normal operations of the solid state memory device, wherein the threshold value is less than the first threshold value and wherein the second threshold value is less than a warranty limit temperature; and
based on determining that the operating temperature of one of the plurality of solid state drives exceeds the second threshold value, generating an alert that the second threshold value was exceeded.
